We try our best to spot snipers all the time in games, but in real life, spotting them is way harder. They're trained to be practically invisible; it makes sense.

The sniper photographs above, which were originally shared by Vice, come from artist Simon Menner. Menner captured snipers from the German Army as they hid in nests (which are holes, basically). Here are a few more photographs, all of which hide snipers. Can you spot them all? If you want, you can even use Kinja to click on the part of the picture you think hides a sniper, and annotate it for others to see.
